A sixth sense - enhancing the real-space with gestures

Gesture into thin air, to control projections of a computer interface to objects in front of you. With the combination of off-the-shelf technologies like a small projector, a video camera, a cellphone and a computer you can enhance yourself.

The gestural metaphors for taking a picture, making a telephone call or looking at a watch are intriguing. As the components for this technology cost about 350$ right now, I suppose a lot of disruption will happen in the cellphone business in the next months.
